BINDING-MACHINE.

Application filed May 1, 1915.

T 0 all whom t may concern:

Be it known that I, ALBERT F. Pnns'roN, a citizen of the United States, residing at Boston, county of Suffolk, State of Massachusetts, have invented an improvementin Binding-liiachines,` of which the following description, in connection with the accompanying drawing, is a specilication, like characters on the dra-wing representing like parts. l

This invention relates to improvements in binding machines.

Boot, slioe, garment and other patterns or sheet forms oit card board, paste board, compressed librous materials and compositions having similar properties, are used in cutting out desired shapes and sizes of dilierent materials. The patternis superposed upon the material and the operative then passes a knife or other cutting instrument around the edges of the pattern thus cutting out of the material one or more articles of the pattern shape. It is essential to the continued use of such patterns that their edges be reinforced and protected against natural wear and against injury by careless cutters. Metallic binding applied to the pattern edges efficiently protects'and coincidentally insures Y greater case and accuracy in cutting. The binding employed, as sold to the trade, is in the forni of U-shaped or flanged strips of flexible sheet metal and is adapted to cover the pattern edge, its flanges overlapping the adjoining portions of the adjacent pat tern faces. This binding is usually applied as one continuous strip running around the pattern rather than being applied in sections. This continuous binding is applied to the pattern edge and pressed thereon. It is necessary to bend the binding in' order to secure it to corners of patterns and, in order to insure the ht oic the binding to a corner edge and to insure a symmetrically protected corner, it is essential to remove a small portion of the binding-to cut a notch therein. Unless the notch is made at the exact point, an ill-litted corner results detracting 'from the value of the pattern, if not entirely destroying its utility. Practice has shown that if a portion ot' the binding yiiange is not removed a roughened or burred corner will result. This defect is most eii'ectively overcome by cutting out a triangular piece of metal from the flanges of the binding strip, the apex of the cut being opposite the apex or" thc angle of the pattern. To accom- Specication of Letters Patent.

plish this accurately it is necessary that the point, at which the ilanges of the binding strip are to be cut, be determined when the binding strip is adjacent the pattern edge and that the flanges be cut when separated from the pattern.

The object of this invention is to provide a high-speed power binding machine for aftixing protective binding to pattern edges.

Another object is to provide a binding machine with a rapidly functioning lcutting means by which notches can be expeditiously made in the pattern binding.

Another object is to provide means to insure the notching of the binding at anv predetermined point therein.

it is a further object to provide a machine wherein the pattern and partially attached strip may be positioned at a notching gage when the strip is held adjacent the pattern edge corner and the notch may be cut at the point indicated by the gage when the bindinfr is separated from the pattern.

ln order to aliord an understanding of this invention, va selected embodiment has been illustrated in the accompanying drawings and will now be described.

In this selected embodiment, the power binding machine has a base 1 secured to' a suitable supportfsuch as a bench 2. The

frame 3 which comprehends the gear and shaft housing 1, at the driving or power end, has four laterally projecting arms which terminate respectively, at the worlr end of the frame, in the cutting apparatus, the upper feed and pressuie roller, the lower feed and pressure roller and the means for elevating the lower roller. Power is transmitted to the machine by a belt (not shown) which engages step pulley secured by a set screw 6 to the end of the power shaft 7 which has its bearing in the frame. The speed of the main shaft T is varied by means of shifting the belt on various steps of the pulley, and for that purpose any type of belt shifter may be employed. The main shaft has integral therewith a worm 8 which engages a gear 9 fastened to the upper feed and pressure shaft 10. Mounted upon this shaft 10 and revoluble therewith is the smaller gear 11 which meshes with the twin gear 12 mounted upon the lower feed and pressure shaft 13, so that these two shafts, which carry at their work ends the upperl and lower feed and pressure rollers. reupec` tively, will be revolubly actuated in oppo site directions, at the same rate of speed and will thus feed forward a pattern placed therebetween.

The uppermost or cutter shaft 14. has mounted thereon at its rear end a pinion 15, shown in dotted lines in Fig. 2, which meshes with the gear 1G mounted on a stud shaft 1T. The cutter shaft 14 terminates at its power end in an end bearing cap 18. The pinion 19 is concentrically superposed on` the gear 1G and secured to the stud shaft 17. This pinion meshes with the gear 11. The cutter shaft 14 is thus rotated at a higher rate of speed than that of the feed rolls* in practice, the speed ratio of approximately five and one-half to one has been found eilicient. The gear 9, secured to the shaft 10 by a suitable set screw shown in Fig. 1, has countersunk on its rear face a steel bearing plate 21 which offers a bearing to the power ends of the shafts 13 and 14 and the cap 18 of the cutter shaft-thus preventing any possible lateral thrust. The three sha ts are suitably journaled and supported in the frame and frame arms.

The upper feed and pressure shaft 10, at its work end, extends through the casing arm and carries keyed thereto the upper feed and pressure roller 22, and the retaining screw 23. The lower feed and pressure shaft 13 has a similar roller 24. T hc peripheries of these twin rollers 22 and 24; are beveled so that the greatest diameters are opposed and are somewhat back of their front faces.

The frame casing carrying the lower feed and pressure shaft 13 at the work end'is reduced and has slidably mounted vthereon a sleeve 25 to which is secured a handle for pushing the same inwardly against the action of the washer spring 26. This sleeve is secured against rotation by means of a lug projecting from the casing and engaging a guideway in the sleeve. The sleeve 27, also mounted on the reduced casing arm and carrying at its front end and next to the lower feed and pressure roller the different sized rear positioning` rollers and the fin back guide 28, is adjacent the sleeve and normally bears tliereagainst. This roller sleeve is secured against rotation by means of a lug on the rear sleeve7 which is adapt-ed selectively to engage slots or guideways 29 in the roller sleeve, a slot being opposite each roller and the fin Q8.

Tt is necessary to remove the pattern and binding from the work rolls to cut a notch in the binding when an angle is encountered in rolling and pressing on the binding strip. The facile disengagement of the pattern and partially attached binding is effected without stopping the machine by means which cause the separation of the two feed and pressure rollers. This is the function of the mechanism carried by the lowest arm of the frame which effectuates the elevation and depression of the lower feed and pressure roller 211 into and out of operating` position with relation to the twin roller The casing arm has an end opening for the lower feed and pressure shaft 13 whereby this shaft may be moved in the vertical plane of its axis thus permitting the two rollers to be moved apart while the machine is running. A vertically. adjustable bearing is provided for the shaft 13. It comprises a cylindrical guide 30 which has a transverse central. boring forming the shaft bearing and a threaded reduced portion or stem 3Q adapted to be received within an interiorlv threaded cylindrical nut 33. The guide 3l) and its engaging nut 33 are slidably positioned in theyertical way 31, shown in dotted lines in Fig. 1, which extends through the frame arm containing the lower roller shaft 13 and the lowest frame arm. The nut, preferably closed at its bottom face, rests upon the stud shaft 34s which has a portion of its periphery beveled away, forming a flat surface 35. The function of this flat surface is to provide means whereby, upon the rotation of the stud shaft, the mit, and therefore the guide 30, may be cammed into elevated or depressed position accordingly as the periphery7 or the flat surface of this shaft is presented to the nut through manual rotation of the stud shaft by meahs of a bar lever 36 secured therein. A limited path is provided for the lever 3G by an elon gated opening 37 cut in opposed sides ofthe lowest frame arm. A weighted headV 3S. shown as a ball, is affixed to the lever end so to retain the shaft that its periphery is presented to the nut. The lower roller shaft 13 is thus normally elevated and the lower 'L roller held in effective operating position with relation to the upper roller. The rollers drop apart when the head is raised.

The cylinder nut 33 is provided with a plurality of apertures 39 in which a small pin lever 40 is adapted selectively to be inserted. Graduated adjustment of the nut on the threaded stem 32 is effectuated through rotation of the nut by means of this lever 40. The operating space between the lower and upper rollers thus may be adjustably varied for different thicknesses of patterns or binding strips.

It is necessary, in order to preserve the contour of the pattern corners and to obtain a smooth edge, to cut a small miter or notch in the anges of the U-shaped binding strip. Practice has demonstrated that the most symmetrically bound and therefore the most efficiently protected corner is one where the apex of the flange notch is exactly opposite the apex of the pattern angle. This result is accurately7 accomplished by holding the partially attached binding strip against the pattern edge up to the corner, then by positioning a gage in the fianged strip at the apex of the angled pattern corner, whereby the point at which the apex of the notch to be cut in the flanges of the strip may be indicated with precision on the strip, and, finally, by moving the binding strip, partially attached to the pattern, while retentively held with relation to the gage, to the cutting element whence the notch is unerringly cut. Such is the function of the cutting or nctching member secured to the work end of the topmost shaft which consists primarily of the cutting means and the mechanism for correctly positioning the binding strip.

The topmost or cutter shaft arm of the frame has, at its work end, a reduced portion 43 and mounted thereon is the collar 44 which is centrally bored to fit the reduction and is adjustably secured against movement thereon by means of the set screw 45, shown in dotted lines in Fig. 11. Y The collar 44 has a pair of threaded holes 46 therein, which are adapted to receive in threaded engagement suitable screws 47, inserted through the holes 48 in the block 49,' by which means the block 49, bearing the notching means, is secured to the collar and thus is carried by the uppermost frame arm.

The block 49 has a vertical slot 50 in which are positioned the die 51 and the cutter 52. The die is secured against movement in the vertical slot by means of the setl screw 53. The rear face of the die, which as shown is fiush with the surface of the block, also impinges against the end face of the reduced portion of the frame arm and collar 44. The die 51 has a bearing face-54 which has a circular hole 55 therein. The cutter shaft 14, at the work end, has a reduced portion u 56 which is adapted to fit into the hole 55 and to rotate freely therein. The cutter 52 is slidably secured against the bearing ace 54 of the die and is adapted to reciprocate vertically thereon. Reciprocatory movement is imparted to the cutter by means of the eccentric stud 57 on the end of the reduced portion 55 of the cutter shaft. This stud bears on its periphery a roller 58 which is adapted to reciprocate transversely in the lateral slot 59 which is cut in the face of the cutter 52 and is of a width but slightly greater than' the diameter of the external edge of the roller 58. Thus, the rotary motion of the shaft 14, through the medium of the eccentricity of the stud, its roller and the lateral slot, is translated into the vertically reciprocatory motion of the cutter.

' The bearing face 54 of the die bears a flange 60 which forms a lateral bearing guide for the reciprocating cutter 52. The flange, opposite the hole 55, is arcuately cut away at 61 to allow full play to the eccentric stud roller in its traverse of the slot 59. The edge of the cutter, normally adjacent this flange, is partially beveled away, leaving a double-edged tooth 62-substantially of a triangular configuration. The die, at its upper end, has an opening cut through both its flange and face, forming pairs of shearing edges to coperate with the cutting edges or the double-edged tooth. The vedge 63 of the die flange and the edge 64 of the die form shearing' edges for the lower cutting edges of the triangular tooth; while, the upper edge 65 of the flange cut and the upper edge 66 of the die form shearing edges coperating with the upper edges of the tooth. This opening in the die and flange is made at an angle to the flange 60 and forms, through the die, a beveled or sloping the block 49 and drop away. Lateral move-l ment of the cutter is prevented by the flange 60 of the die and it is held thereagainst and wear taken up by means of the screw 70 inserted in a threaded aperture in the side of the block 49 and adjust-ably locked by the nut 71. A similar screw 72 ada ted to beV adjustably locked by the nut 73, is inserted in a threaded aperture cut through the block 49 to the vertical slot 50, and, bearing against the cutters rear face, positions it against thebearing face of the die and similarly may be changed to take' np wear. The

width of the tooth 62 is such that, when midway its stroke, it will be positioned in the center of the opening formed bythe transverse cut made through the die 54 and its flange GO, and space at such position is afforded for the tv-:o flanges of the U-shaped tbinding strip to pass the one above the tooth and the other belovf. Further, the vertical movement of the toot-h is so limited that it is impossible for the tooth to slide above or below the channel, leaving it completely open, and hence, the metal binding can only enter the path of the tooth ivhen the tooth is midway and the flanges of the binding are placed on either side thereofin effective operating or cutting position.

A gaging and movable positioning appa.- ratus for the flanged binding strip is pro-- vided. This apparatus operates in such Way as to assure the cutting of the not-ch in the binding so that the apex of the triangular cut will be precisely opposite the apen of the pattern angle. ln binding a pattern, the operative usually starts binding along a straight edge. rllhe pattern is removed from the .feed and pressure rollers when a corner is approached and, ivith its partially attached binding, is elevated to this apparatus supported on the frame side of the block The binding is placed Within a clamping member and the pattern angle or corner is positioned with relation to the gage and the binding then clamped. rlf'he clamping member which is slidably mounted, is then moved so that the binding flanges are presented to the notching means and are cut at such predetermined point vwith the result that ay perfect, symmetrically bound edge must ensue when the strip is thereafter returned to the rollers and rolled on the pattern edge. At the time of notching, the pattern is separated from the binding so that injury to the pattern corner is impossible and interference by it with the accurate notching and positioning of the apen of the notch avoided. it is thus seen that the apex of the triangular notch to be cut is determined While the binding is held against the pattern edge and that, in cutting the notch at the predetermined point, the pattern is sepa rated from the binding.

[i support il is secured to the block Lif) by means of the screivs T5. A. slide 76 is adapted to reciprocate in a runivay formed in this support and is retained therein by means of the over-hanging flange 77. rllhe reciprocatory motion of tne slide is limited by means of the pin T8 which are adapted to slide into and out of engagement with the slots 79 cut in the bottom. of each end of the support. A trough 80 is mounted upon the slide 76 at an angle. This-trough is preferably integral with the slide and moves therewith. rl`ho arm Si, which forms one member of the clamp, has tivo preferably integral base plates S2 and 83 which are adapted to reciprocally slide m the trough. riheinotion of the base plates and hence of the arm 8l is ineens? limited by means of a detent Set comprising a rectangular piece of metal secured at the substantially midvvay point of the trough. The arm 8l and its preferably integral base plates 82 and. 83, are slidably secured to the trough by means of the angled strap 85 fastened by the screws 86 to the side of the arm and having its angled portion 87 impinging upon the underside of the trough. The edge S8 of this strap portion 87 is cut away to alloiv full play to the sliding arm 81 in its forvvard movement above the trough.

The rear base plate S2, integral With the sliding arm Si, has a pin S9 on Which is pivotally mounted the cooperating clamping member 90, shown in Fig. 8. rlhis clamp 90 has hole adapted to receive the pivotl pin S9. The forivard end of this clamp bears projeeting finger 91, the tip of Which is beveled and functions as the gage 92. Grooves 93 are cut in the inner face of the clamp, one on each side of the finger, and are adapted to receive therein the flanges of the i-shaped binding strip when it is positioned in the clamping and gaging means. These grooves 93 extend only a portion of the Way back on the clamp as the inner clamp face is cut away with the result that the clamping function is attained between the forward portions of the arm 8l and the clamp.

rEhe arm 8l, at its forward end, has a reduced portion or tip 9i which is of a height slightly greater than the finger 91. The end portion of the finger is adapted to impinge against the tip 94 substantially along the middle thereof, the gage 92 and the tip end coincidentally terminating, The side of the clamp 90 opposite the finger has a reduced portion 95 which insures clearance of the bach of the die by the clamp in its rearward movement. The end face of the arm 81 adu jacent the reduced port-ion or tip thereon and the similar end face 9G of the clamp are cut off at an angle to their longitudinal axes in order that, when the arm and clamp are withdrawn to rearward position and the slide moved to its inner position, the ends ofthe arm and clamp may slide past the rear face of the die. The Width of the tip Si is smaller than the flange opening of the die 5l and hence, When the slide and arm are fully retracted, the arm tip 9e :and finger Si may pass ivithin the opening and the flanges of the binding strip retained in the clamp may be presented to the path of the curing tooth 52, as shown in Fig. 5.

rlhe modification shown in Fig. l2 is'of a clamping member 97 Which'is employed. in place of the clamp 90. This member 97 is similar to the clamp 90 but is Without the A. rejecting finger, gage and grooves, and functions solely as a clamping member. lllhen the clamp 90 is used, the edge of the pattern 98 (shown in dotted lines in Fig. 3)

ilo

is held against the binding strip between its flanges and the pattern is pushed inwardly Iuntil it touches the gage 92 and the binding is then clamped. But, when employing this modification 97, the operative simply slides the binding strip between the clamping members, positions the angle of the corner of the attached pattern opposite the end 94 of the arm 81, clamps the binding in such position and thence proceeds with the notching. IThus, it is evident that, in using the modified clamp, the operative relies upon his eye to position correctly the binding strip in the clamping member.

The operation of this machine is simple, rapid and eflicient and does not require the services of a skilled operative. In binding a pattern, the operative holds the binding strip on the pattern edge, raises the lever 36, which through the agency of the adjustable bearing means depresse's the lower roller, the pattern edge and binding are held between the rollers, and the lever is depressed and the lower roller is elevated to effectiif'e operating distance from the upper. rlhe pattern is then automatically fed between the rollers, due to the fact that they are rotating in opposite directions, and the binding is pressed thereon. Vhen a corner is approached the operative raises the lever 36, the lower roller is depressed, and facile disengagement of the pattern is permitted. The operative removes the pattern to notch the flanges opposite the corner. The free end of the partially attached binding strip is then presented to the gaging device. The flanges of the strip are placed in the grooves 93, the gage 92 entering within the channel of the strip. The binding with the pattern held thereagainst is slid inwardly until the apex of the pattern corner angle comes to rest against the gage formed by the beveled end of the linger. The gage thus indicates the precise point, where the apex of the binding notch should be, in order that such apex may be opposite that of the pattern corner angle. Such position is shown in Fig. 3. rIhe operative then grasps the arm and clamp which causes the binding strip to be positively retained in such position. The arm and clamp composing the clamping member are pulled to rearward `position while the slide is pulled to inner position when the pattern will be separated from the binding strip by the die and cutter and the Hanges of the binding strip will be presented to the path of cutting teeth. Such position is shown in Fig. 5. The slide and the clamping member are both immediately returned to normal position, the clamp released and the pattern removed. The binding having thus been notched, the pattern is again placed between the feed and pressure rollers, and the pattern and binding are again automatically fed therebetween and the binding pinched on the pattern. In pinching on the binding strip at the corners it frequently occurs that the rollers run across the adjoining pattern'edge to which the strip has already been aflixed. In such case a groove is pressed by the beveled peripheries of such rollers as those to which reference has been made. Further, with strips of certain metals, slightly rounded'top and bottom faces of the strip result. Such defect may be overcome by clamping the substantially flat rollers shown in Fig. 15. These rollers are illustrated as beveled each way from their opposed lines of greatest diameter about three degrees from the horizontal. However', rollers having horizontal or flat peripheries may be employed. A binding strip which may effectively be employed with the flat and substantially fiat rollers is shown in enlarged sectional detail in Fig. 16. This strip has outwardly flaring side walls 100 and each carries longitudinally its length a hair-line rib 101. This rib is formed, inv this selected embodiment, byv

turning in the edge of the binding strip substantially one one-thousandth of an inch. Then pressed upon the pattern edge by the flat or substantially flat rollers, the rib is embedded in the pattern both top and bottom. A pattern thusbound, not only will have a more retentively allixed reinforcement but will lie flat upon the material to be cut.
